搜索

The second research has also got that a function of slopes to C values is monotone decreasing function when target circles are bigger than distractors circles.

研究二针对目标圆大于干扰子圆大的条件，得到的目标搜索斜率对C值的函数也是单调递减函数，并确定了平行搜索与系列搜索的临界点〓（0.497）。

When target values are bigger than distractors values, the two experiments have found that a function of slopes to C values is monotone decreasing function, that slopes are identical under same C values, and that there is no significant difference between circles stimulus and triangles stimulus under same C values.

实验发现在目标大于干扰子条件下，目标搜索斜率对C值的函数是单调递减函数；C相等时的目标搜索斜率也相等；C相等时的圆和三角形两种刺激形状之间的目标搜索斜率无显著差异。

For example you search music in Baidu Google, can see in the relevant search of nethermost for instance the key word of and so on of network of classical music, rock and roll, Orphean music, these results are according to the search the capacity comes of sort.

例如你在百度google搜索音乐，会在最下面的的相关搜索中看到比如古典音乐、摇滚音乐、好听音乐网之类的关键字，这些结果是根据搜索量来排序的。

The effectiveness of this method depends basically on two values,Гmin the search is faster for larger Гmin and the size of Pref (RE (the search is faster for less prefixes), where Гmin donate the shortest path from the initial state to a final state of the Nondeterministic Finite Automaton and Pref the prefixes of length Гmin for all the strings matching the regular expression. The size of Pref can be exponential in m and for multiple expressions matching the Pref will be much larger.

现有的正则表达式搜索算法性能较好的是多模式过滤类型的算法，此类算法严重依赖于两个因素，从NFA的初始状态到终止状态的最短路径Lmin和正则表达式所表达的语言的前缀集合Pref的大小，Lmin越长，搜索速度越快，Pref越大，搜索速度越慢。

Based on the principle of optimality,the search problem is then transformed to an equivalent problem of deterministic distributed parameters system,represented by a second order PDE.

采用分析的方法来研究随机运动目标的最优搜索问题，并将原问题转化为由一个二阶偏微分方程所表示的确定性分布参数系统的等价问题，推导出随机运动目标的最优搜索问题的HJB方程，并证明了该方程的解即是所寻求的最优搜索策略。

And points out that the random of search range could lead to repeated search or overlong search time.

但存在由于搜索范围的随机性导致重复搜索及搜索时间过长。

Critical to any discussion of efficient pathfinding within a game is the notion of hierarchical maps.

要进行有效的A*搜索，对于任何专门的搜索，很重要的一点就是出发点和目标点之间的距离过大，或者搜索时间太长。

Along with the rapid development of Internet technology and exponential progressional increase of network resource, the tempo of search engine decides the using rate of Internet resource to a large extent, and the problems in existing search engines make the academia ceaselessly do some research in every kind of search theory and technique.

随着互联网的高速发展和网络资源的指数级数增长，搜索引擎的发展水平在一定程度上决定着互联网资源的利用率，但现有搜索引擎存在的问题，促使学术界不断进行各种搜索理论和技术的研究。P2P全文搜索引擎作为一种全新的搜索方式，日益受到学术界的关注，各种改进的搜索算法被相继提出，并应用于实践。

In the first paper,we survey the history of direct search method, and discuss fourdirect methods respectively,which are simplex method, pattern search method, linesearch method and quadratic interpolation model method.

对单纯形法、模式搜索法、线性搜索法、二次插植模型法这四类主要的直接搜索方法的主要思想、算法的起源、发展状况及其特点分别作了介绍。

Current, regular to searching the permutation of the result acknowledge spends search user inferior, the permutation that the user of close 2/3 expresses not to know to search a result is regular.

目前，搜索用户对搜索结果的排列规则认知度较低，近2/3的用户表示不知道搜索结果的排列规则。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.

他拔下桅杆，把帆卷起，系住。
